T-model based algorithm for a non-saturable and insensitive to `TR´ changes control in induction drives

An induction motor working with no torque limitation and no core saturation are the main purposes of this paper. To do this, a complete and independent flux and torque control is required by decoupling the respective regulating loops. The authors present a new induction motor state observer which is insensitive to `TR´ changes developed for the T-model that gives an accurate measurement of motor internal parameters, particularly flux and torque
